CHP, a large part of my living is delivering specialized electronics. I run one of my trucks in the Tri-Boro New York Area 2 days a week just delivering walk thru metal detectors to schools and Universities. We recently started a delivery sweep covering South Jersey and the Philly area. It is a much bigger problem than the occasional news blurb we see. Back when I was a kid, you had words and maybe a trip to the baseball field for some fist-a-cuffs after school if things couldn't be ironed out. Now, someone gets a chip on their shoulder and they are looking to ventilate someone. My have times have changed.
Even though I agree this could be a issue in "some" areas, personally I feel this video is a scare tactic like the drug commericals on tv. Video's like this are used to drum up some kind of voting for political figures and do not really help solve problems.
Ok the hand guns I will believe to a certain point. But have you ever tried walking with a 4' shot gun stuffed in the leg of your pants? It's not that easy, and don't ask me how I know. LOL
